Description

The present disclosure provides a covering or separating element, such as a sheet or foil (also called a drape), and an electromechanical antibacterial lock that is integrated or can be integrated/attached to that element. , a germ-proof lock for transmitting electrical energy and/or electrical control signals from wiring on the non-sterile side to wiring on the sterile side, in particular to a sterilization barrier according to the preamble of claim 1.

As the operating room becomes more digital, the integration of electronics and software in electrically driven surgical motor systems increases. Since electronic elements can only be sterilized with great effort and restrictions, the basic objective is, for example, a sterilization area (instruments that can be reprocessed without restrictions and manipulated by the surgeon without restrictions) and Providing or isolating the surgical drive in a non-sterile area (instruments critical to reprocessing and which must not be touched by the surgeon). One of the advantages of this concept is that minimal mass (volume) must be handled by the surgeon as essential parts of the surgical drive are moved to a non-sterile area. These two areas (sterile area/non-sterile area), on the one hand, must be electromechanically brought into contact prior to surgery, on the other hand alternately decontacted/disconnected during surgery, and on the other hand. It must be brought back into contact with the sterile area. Ideally, this task is performed by sterile personnel at the operating table in accordance with sterilization requirements. This requires a sterile isolation concept that is compatible with current surgical hygiene requirements and that is reliably viable.

Accompanying FIG. 3 shows the general arrangement of sterile and non-sterile areas separated by a sterile barrier and which may be provided for the purposes of this disclosure.

For example, a robot 100 including actuators or holding devices is placed in a non-sterile area U shielded from the surrounding sterile area S by a drape 101 . The drape has at least two passageways/openings 102, 103, one passageway 102 of which is configured as a passageway opening for the holding arm of the robot 100, and the other passageway 103 which is non-sterile. It is configured to connect a sterile cable section 104 in sterile area S to a non-sterile cable section in area U (not shown). For this purpose a connector device 105 is provided. In this case, the cables in the sterilization area S are connected to a controller 106 for controlling the robot 100, for example.

Other basic applications include, for example, contacting a control module or robotic arm in a non-sterile area with a drive motor in a sterile area. For example, it is already known to attach so-called protective shields to sterile motor cables. The protective shield is arranged to reduce the risk of contact with non-sterile components during the connecting/plugging process or plugging the motor cable into the non-sterile control unit. This so-called protective shield is also called a sterile protective cap.

However, its significant drawback is that after one connection/plugging, the motor cable becomes contaminated, at least at its connector area, and the cable cannot be removed/unplugged and returned to the sterile instrument table within the sterile area. It is to disappear. This prevents different drives from being used for different surgical steps during surgery.

Furthermore, in the state of the art there are so-called sterilization barriers in the form of cover sheets or separation sheets that separate sterile and non-sterile areas and have interfaces or ports through which supply lines can pass. To this end, such an interface has, for example, a number of openable and closable flaps forming corresponding passages as required.

US Patent Application Publication No. 2018/0145443 discloses an electrical connector associated with an electromagnetic tracking device that is movable and trackable within a patient's body. Thereby, in a multi-part electrical (plug) connector system used in a medical environment, a first section of the connector system is arranged to perforate a moldable sterilization barrier, for example made of textile material, this arrangement comprising: While connecting the first portion of the connector system to the second portion of the connector system. However, as can be seen in particular from FIGS. 9, 11A, and 11E of US2018/0145443, the proposed perforation does not (locally) restrict fungal pathways at each spot. is disadvantageous. As a result of uncontrolled contamination in the drilled holes, any sterility that may have previously existed is naturally compromised or terminated.

US Patent Application Publication No. 2018/0049833 discloses a sterilization barrier for use with surgical robotic systems. The sterility barrier may include a housing configured to interface with a tool driver coupled to the robotic arm and removably receive a surgical tool. The sterile barrier housing has a sterile flexible fabric extending therefrom, the housing and flexible fabric being formed in two or more planes, a sterile side on which the surgical tools are placed and a non-sterile side on which the tools are placed. and define The housing may have at least one pin-shaped electrical connection configured to operatively connect with at least one complementary electrical connection provided on at least one of the tool driver and the robot arm. Thus, the fabric is formed with pre-made openings arranged or configured to pass through each of the pin-shaped electrical connections.

US Patent Application Publication No. 2016/0058513 discloses another sterilization barrier known in the prior art. Here, a surgical system includes a first element having a seat for removably receiving a surgical instrument for surgical use. Two connectors, wherein at least one of the two connectors provided with an electrical connection for engaging the other connector is in a first retracted stop position for electrical connection with the other connector. It is adapted to be controllably movable between the second advanced position.

Furthermore, the Applicant's DE 20 2007 002 332 A1 discloses a medical sterile cover in which plug connections are inserted into corresponding plug sockets via respective openings provided in the cover. be done. In that regard, a strong bond is proposed for sealing.

It is therefore an object of the present disclosure to avoid, or at least mitigate, the drawbacks of the prior art. In particular, interfaces present on the operating table for repeated adaptation/separation of sterile application parts and non-sterile surgical parts, such as electromechanical interfaces, should be secure, hygienic and/or cost effective. is.

According to the present disclosure this problem is solved by a sterilization barrier having the features of claim 1 . A further advantageous development of the disclosure is the subject matter of the subclaims.

The core concept of this disclosure is essentially a simple sterile isolation element (sterility barrier), for example in the form of a sheet, foil or drape, and a sterile isolation element, such as a mandrel, from one side of the sterile isolation element. an electromechanical lock/coupling having at least one connecting pin arranged and configured to be insertable/insertable/inserted into and protruding from the other side of the sterile separation element. . As a result, the at least one connecting pin is sterilely (proximately/directly) surrounded by a sterile separating element, or the sterile separating element is sterilely surrounded over the entire circumference of the at least one connecting pin. Fitted, the connection pins can be connected by lines at at least one end/end section, for example using plug sockets or plugs.

The at least one connecting pin may have two rod ends/pin ends that are essentially similar/identical to each other, thereby having or from corresponding socket-shaped/sleeve-shaped connecting elements. It should already be noted at this point that two sockets that are configured similar/identical to each other can be plugged on both sides. Alternatively, however, in particular, one end of the non-sterile side of the sterile separating element is preferably formed as a pin (smaller diameter) and the other end of the sterile separating element is preferably a sleeve/sleeve (larger diameter). It is also conceivable for at least one connecting pin to be formed with mutually different (two) pin ends, such that it is formed as a plug socket. Thus, on one side (non-sterile side) a kind of socket/plug-socket with (larger diameter) sleeve-shaped connecting pins may be inserted for the connecting pins passing through the sterile separating element, On the other side (sterile side) a kind of plug/insertion pin with a (smaller diameter) pin shape may be inserted. The latter means, for example, that a sterile electromedical instrument, to which electrical cables (with pin-shaped electrical connections) and cable plugs are usually fixed, can be connected without an additional (intermediate) adapter to at least one connection pin. (or its sleeve-shaped pin end). The same applies to the so-called extension cables on the non-sterile side, the sockets at one end of each of the extension cables with at least one sleeve-shaped connecting pin also being inserted into the sterile separating element without an adapter. It can be electrically connected to a pin end formed as a pin of one connecting pin.

Preferably (alternatively or cumulatively), at least one connecting pin is held on one side of the sterile separating element in/by the first housing, the first housing being the plug socket and/or at least one line forming a receiving shaft for a plug or fixed to at least one connecting pin is led out of the first housing. Here, it is not necessary that the same type of receiving shaft or plug socket is arranged on both sides of the sterile separation element, but preferably the plug is arranged on one side, the non-sterile side of the sterile separation element, preferably sterile. Note also that the plug socket may be located on the other side, which is the side.

Further preferably (alternatively or cumulatively) a second housing is provided on the other side of the sterile separation element, the second housing being connected via the sterile separation element (as sterile intermediate layer) to the second housing. It is adapted to be pressed against one housing so that at least one connecting pin protrudes through the sterile separation element into the interior of the second housing. Therefore, the second housing may preferably be formed as a receiving shaft, more preferably a connecting shaft, so that a further plug socket or plug can be inserted into the second housing and connected with the at least one connecting pin. The second housing is held at the pin, ie at the first housing.

Such a design is particularly suitable for unidirectional sterilization sheets as it is simple, inexpensive and reliable.

In other words, according to the present disclosure, a flat, preferably flexible sterilization element for sterile separation is provided. A sterile separation element is arranged or provided or formed to fit between the first plug connector/housing and the second plug connector/housing of the plug connection/electromechanical lock and is therefore provided or configured to provide or achieve sterile isolation of the plug connector.

The plug connection may preferably be a force-lock connection and/or a form-fit connection. When connecting the first plug connector/housing and the second plug connector/housing, the sterile separation element may preferably be placed between the plug connectors and conforms to the geometry of the plug connection between the plug connectors. Fits substantially alone.

As used herein, the term "sterile separation" specifically refers to separating sterile elements from non-sterile elements such that the sterile elements are not contaminated at least at predetermined points of contact or points intended for manual manipulation/contact. should be construed to mean that

Advantageous embodiments are claimed in the subclaims and are explained in more detail below.

For example, the sterile isolation element may be foldable and/or flexible. The sterile separating element may be provided for one-time use (in English, single-use), eg as a disposable item. In this way a secure and hygienic sterile separation means can be provided in a simple manner.

The plug connection may be an electrical plug connection. One of the plug connectors of the plug connection may be of the male type (connection pin) and the other of the plug connectors of the plug connection may be of the female type (plug socket).

A sterile separating element is provided to be pierced by several (or several) electrical connections of the male plug connector (connection pin). In particular, a sterile separating element may be provided to form an intermediate layer between the female plug connector/plug socket and the male plug connector (connecting pins) during their plugging process.

In an advantageous embodiment (alternatively or cumulatively) the sterile separation element is dimensioned such that in use the flat element forms a stulpe over one of the plug connectors. good too. This allows the plug connector to be easily gripped without risk of contamination.

For example (alternatively or cumulatively), the sterile separation element may be impregnated with an antiseptic. For example, disinfectants may be based on alcohol (ethanol or 2-propanol) and mesetronium ethyl sulfate. Additionally, the antiseptic may contain lipid substances so as not to cause skin irritation. The planar element may thus be a hand sanitizing wipe. The disinfectant may also include one or more of the following. Oxidizing agents, peracetic acid, hydrogen peroxide, halogens (iodine, chlorine compounds), ozone, phenol derivatives (including chloroxylenol, triclosan), aldehydes (e.g. formaldehyde), alcohols, detergents, nitrogen compounds (e.g. benz chloride ruconium) and the like (chlorhexidine, octenidine, polyhexanide). Accordingly, the planar element itself may be sterile/sterile.

Likewise, preferably (alternatively or cumulatively), the sterile separation element may be configured to form a fold over the cable connected to the plug connector in use. This allows an operator to easily manipulate/connect the plug connector without contaminating the plug connector.

According to any or several embodiments, the sterile isolation element may be a foil, drape, or sheet. The sterile separation element may be configured to be puncture resistant. At least the flat element may maintain a predetermined tensile force, for example at least 1 N/mm ² or 10 N/mm ² , ie it may be resistant to tensile forces. Flat elements may also be configured for maximum tensile forces, such as 15 N/mm ² or 150 N/mm ² .

In particular, the non-sterile plug connector may (alternatively or cumulatively) include attachments for attachment to an external stationary object such as an operating table. Thereby, the operator only needs to touch the sterile parts to connect the sterile and non-sterile cables, for example by means of plugging adapters or flat elements.

The present disclosure will be described in more detail below based on preferred embodiments with reference to the accompanying drawings below.

Fig. 2 shows a schematic representation of a sterile barrier in the form of a sterile separation element with an electromechanical lock, in a schematic diagram or schematic basic structure to show essential parts/components of an arrangement according to the present disclosure; A sterile barrier in the form of a sterile isolation element with an electromechanical lock, in particular as a sterile isolation module, according to a first preferred embodiment of the present disclosure (for at least one electrical connection pin with two free pin ends) Fig. 2 shows a schematic diagram of a constructed sterilization barrier; A sterile barrier in the form of a sterile isolation element with an electromechanical lock, in particular as a sterile isolation module, according to a second preferred embodiment of the present disclosure (for at least one electrical connection pin with two free pin ends) Fig. 2 shows a schematic diagram of a constructed sterilization barrier; Shows the general layout/division of sterile and non-sterile areas.

FIG. 1 shows a sterile barrier in a schematic diagram or schematic basic structure to show the essential parts/components of an arrangement according to the present disclosure, which comprises a flexible sterile isolation element 1 (hereinafter simply referred to as a sterile drape) and an electromechanical lock 2 located in/on the sterile drape 1 and having at least one electrical connection pin 9 individually penetrating the sterile separation element 1 2 and a (first) line bus 5 consisting of several/multiple lines/cables leading to the lock 2 in the non-sterile area and a corresponding several/multiple lines/cables consisting of the lock in the sterile area. and a further (second) line bus 5 extending away from 2 .

Specifically, the sterilization drape 1 is an antimicrobial cloth or (antimicrobial) foil provided and configured to separate a sterile area from a non-sterile area. For example, the sterile area may be a surgical area/operating room in which robotic arms or various drive and/or control devices/medical devices are located, these instruments themselves constituting non-sterile areas. and therefore must be sterilely separated from the sterile area. To this end, such non-sterile areas may be surrounded/covered by the illustrated sterilization drape 1, but without damaging/destroying the germ-proof sterilization barrier, for example electrical It must be ensured that the devices, energy sources or control systems are electrically connected via the sterile drape 1 with the (medical technical or surgical) devices in the sterile area, such as surgical electrical drive handles, lighting means. must.

This basic structure or schematic basic structure corresponds to the configuration shown in FIG. 4, so reference can be made to the above description with reference to FIG. For maintenance of sterility, an electromechanical lock 2 according to the present disclosure is provided, which is described in more detail below.

In principle, the electromechanical lock 2 according to the present disclosure has several, preferably several, connection pins (lock connections) 9, which are preferably supported/ It is fixed and protrudes from the first housing 10 in the form of a mandrel on one side of the housing (hereinafter referred to as the abutment side). The connection pins 9 are spaced parallel to each other.

Each connecting pin 9 has at least one free pin end/free protruding pin end or free end section which is provided and configured/adapted to penetrate the sterile drape 1 . For this purpose, one pin end of the connecting pin 9 may, for example, be pointed or sharp, or each of the connecting pins 9 may be attached to the sterile drape without tearing the sterile drape 1. It has a diameter so small that it can penetrate 1. What is important here is that a very small perforation is made so that the pierced connecting pin 9 is surrounded by a sterile drape 1 that fits all around the pin in a germ-proof manner.

Preferably, control electronics are already in the first housing 10, such as, for example, electronics 4 for controlling the batteries of electromedical technical devices/surgical devices or similar working equipment arranged in the sterile area. may be placed. In this case, each electromedical device/surgical device in the sterile area is assigned a device-specific lock 2, e.g. with device-specific control elements or a power supply already present in the first lock housing 10. .

According to a further partially disclosed embodiment shown in FIG. 1, at least one electrical connection pin 9 is connected with a corresponding electrical plug socket 12 of at least one line 5 on the sterile or non-sterile side of the sterile separation element 1. It has a free pin end provided and configured for an electromechanical connection or an electrically conductive plug connection, while at least another line 5 is on the other side of the sterile separation element 1, at the other pin end. firmly connected. A line (cable) is therefore fixed to the other free pin end or the other free end section of each connecting pin 9, which lines (cables) combine to form a line bus (cable harness) 5, This line bus (cable harness) is led to the outside through a housing opening provided on the side of the housing facing the contact side. This cable harness 5 is then electrically coupled to a corresponding medical device (further not shown) within the sterile area.

And generally (as shown in FIG. 1) a holder 6 may be arranged/configured in the first housing 10, e.g. Additionally, the holder 6 may fix the first housing 10 to a (stationary) fixture, such as an operating table.

On the side of the sterile drape 1 opposite the first housing 10 is shown a second housing 11 having a hollow, generally cylindrical/tubular shape, with one end face of the second housing 11 facing the sterile drape. Abutting, the sterile drape 1 is sandwiched between the first housing 10 and the second housing 11 . One free pin end/end section of the connecting pin 9 (which has already been pushed through the sterile drape 1 ) thus projects inside the hollow cylindrical second housing 11 .

These free pin ends of the connection pins 9 are provided and configured for electrical plug-in connection with a connection socket 12, to which also lines/cables are attached, these lines/cables being connected together. to form a cable harness 5 that is equivalent to the cable harness 5 on the other side of the sterile drape. When these plug sockets 12 are inserted into the free pin ends/end sections of the connecting pins 9, the plug sockets 12 engage the sterile drape 1 on the abutting side of the first housing 10 located on the other side of the sterile drape. Squeeze to hold the entire lock assembly.

It should now be noted that the connection sockets 12 shown separately in FIG. 1 may be combined to form a plug shaped to fit the hollow cylindrical second housing 12 so that it can be plugged. Please note.

FIG. 2 shows a first embodiment of the present disclosure, and in the following basically different design features from the example of FIG. embodiment also applies). In this respect, the same words and reference numbers are used for the same components.

In the present example, in contrast to the first housing 10 (with the second housing 11) according to FIG. An insertion shaft is also formed and the plug 13 is adapted to the insertion shaft of the first housing 10 . 2, the fixed line connection 3 shown in FIG. 1 is replaced by an additional plug connection, so that in this example the connection pin 9 has two free pin ends/end sections provided and configured for plug connection with corresponding lines/cables.

Furthermore, in the first embodiment according to the present disclosure of FIG. Configured. Therefore, in the first embodiment according to the present disclosure of FIG. 2, the previously mentioned plug 8 is also schematically shown here as a substitute/alternative for the plug socket 12 shown in FIG.

In short, the present disclosure relates to a sterile separation element 1 for sterile separation, the sterile separation element being placed between the plug connectors 10, 11 of the plug connection/electromechanical lock and thus the sterilization of the plug connectors 10, 11. provided to provide isolation.

A second embodiment of the present disclosure is shown at least schematically in FIG. 3, and only the differences from the first embodiment are described in more detail below.

As can be seen from FIG. 2, the connecting pins 9 are configured as uniform rods forming insertion ends on both sides of the sterile separating element 1, which are insertable like a plug into socket-like insertion sockets. . This means that the sterile separation element 1 must be provided on both sides with a socket capable of contacting engagement with the plug of the electro/electromechanical lock 2 configured on both sides.

However, it has been found that medical electrical equipment usually already comprises an electrical cable already fitted with a plug having simple connecting pins. In order to connect these to the lock 2 of FIG. 2, additional adapters must be provided. In order to avoid such additional components, in a second embodiment of the disclosure, at least on the sterile side of the sterile separating element 1, the end of at least one connecting pin 9 is configured in the form of a sleeve/plug socket. , the lock 2 on the sterile side of the sterile separating element 1 forms a kind of socket into which a plug with at least one simple connecting pin can be inserted, as shown for example in FIG. This variant has the advantage over the variant of FIG. 2 that a plug already present in the medical device can be directly plugged into the lock 2 .
